This is a walkthrough of uploading an image to the facebook wall. I copied this out of an older application, the current facebook API works a little bit different. I think you can see my main point of using a shared facebook object, which you use to do the authentication and also the requests to the API. I took out a few things to make it easier to understand. Apple actually wants you to check for an existing internet connection. I hope it helps.
#synthesize facebook;
//login with facebook
- (IBAction) facebookButtonPressed {
if (!facebook || ![facebook isSessionValid]) {
self.facebook = [[[Facebook alloc] init] autorelease];
NSArray *perms = [NSArray arrayWithObjects: #"read_stream", #"create_note", nil];
[facebook authorize:FACEBOOK_API_KEY permissions:perms delegate:self];
}
else {
[self fbDidLogin];
}
}
//upload image once you're logged in
-(void) fbDidLogin {
[self fbUploadImage];
}
- (void) fbUploadImage
{
NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
resultImage, #"picture",
nil];
[facebook requestWithMethodName: #"photos.upload"
andParams: params
andHttpMethod: #"POST"
andDelegate: self];
self.currentAlertView = [[[UIAlertView alloc]
initWithTitle:NSLocalizedString(#"Facebook", #"")
message:NSLocalizedString(#"Uploading to Facebook.", #"")
delegate:self
cancelButtonTitle:nil
otherButtonTitles: nil] autorelease];
[self.currentAlertView show];
}
//facebook error
- (void)request:(FBRequest*)request didFailWithError:(NSError*)error
{
[self.currentAlertView dismissWithClickedButtonIndex:0 animated:YES];
self.currentAlertView = nil;
UIAlertView *myAlert = [[UIAlertView alloc]
initWithTitle:NSLocalizedString(#"Error", #"")
message:NSLocalizedString(#"Facebook error message", #"")
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"OK", nil];
[myAlert show];
[myAlert release];
}
//facebook success
- (void)request:(FBRequest*)request didLoad:(id)result
{
[self.currentAlertView dismissWithClickedButtonIndex:0 animated:YES];
self.currentAlertView = nil;
UIAlertView *myAlert = [[UIAlertView alloc]
initWithTitle:NSLocalizedString(#"Facebook", #"")
